Definitions
- the present invention relates to the regulators for underwater breathing apparatus.
- Such regulators comprise a box-like body to which a tube provided of mouthpiece is connected, the said body being made from metal or plastic material.
- the realization in plastic material is the one that results economically more advantageous, since the regulator is particularly light and handy, and it results also obteinable at restrained costs.
- a regulator for underwater breathing apparatus comprising a box-like body made of molded plastic material.
- the regulator is provided with a heat conducting element having a first portion so located to receive heat from the user's breath and having a second portion in heat transferring relation to the valve mechanism whereby heat is transferred from the user's breath to the valve mechanism for preventing freeze-up of the valve mechanism under cold ambient conditions.
- Purpose of the invention is to provide a regulator which is able to exchange efficently heath with the exterior, like the regulators provided with a metallic body, whilst maintaining the characteristics of handiness, lightness and economy of realization of the regulators having a body made of plastic material.
- a regulator for underwater breathing apparatus comprising a box-like body of plastic material, from which a tube provided with a mouthpiece departs, and provided with an outlet port, characterized by the feature that the said box-like body of the regulator is provided with one or more metallic inserts integrated in said body.
- said box-like body has a substantially cylindrical shape, and said inserts are disposed on its side wall, in the shape of one or more annular sectors.
- the cylindrical box-like body of the regulator is designated.
- Said body made from plastic material, includes a diaphragm D separating the interior of the body in a first chamber A in communication with the ambient and a second chamber B containing in its inside the device for the regulation of the air flow delivery.
- Said device (not shown) may be of any well known type, and it will not described since it is not part of the scope of the present invention.
- a tube 2 provided with mouthpiece 102 for the inspiration and expiration of the air by the diver branches out.
- an outlet port 201 provided with a non-return valve 301 is formed, the said port 201 being in communication with the tubular element 3 through the hole 103 on the side wall of the latter facing said outlet 201.
- the side wall 101 of the said casing 1 presents two openings 111 in which two semiannular metal inserts 401 are fitted, whose purpose will furthermore be described.
- the peripheral edges of such inserts 401 being provided with swellings 411.
- the operation of the regulator according to the invention is as follows.
- the regulators with body made entirely of plastic material tend to make possible the icing on their inside, mainly due to the difficulty of compensating the drop in temperature due to the expansion caused by the diathermic walls.
- the expansion of the air into the regulator caused by the diver's breathing in should encourage the formation of the above mentioned ice encrustations.
- the metal inserts 401 embedded in the plastic walls of the body of the regulator and acting as heat-exchangers between the inside chamber of the regulator casing and the external environment thanks to the presence of the metal inserts 401 embedded in the plastic walls of the body of the regulator and acting as heat-exchangers between the inside chamber of the regulator casing and the external environment, the quick re-establishment of the temperature balance inside the casing is obtained, and the freezing of the stem which is inside the casing is thus prevented.
- the inserts 401 are, in the case shown, in number of two, semiannular shaped, but it is possible to provide only one insert, disposed near the outlet port of the supply valve (not shown), which is usually positioned radially with respect to the said box-like body.
- the swellings 411 on the external edges of the inserts favour the stability of the connection with the side wall 101 of the body 1.
- the assembling between said inserts and said casing can be made by any known manner, and preferably said inserts are assembled to the casing during the molding operation of the casing.
- the regulator according to the invention can be utilized with the same reliability of those provided with entirely metallic body, having the merit of having been produced at greatly lower manufacturing costs.
